His knife skills are still mostly in the realm of stabbing giants with them, so the vegetables end up in fairly different sizes like the last time he tried to chop them, too (for Gu Xiang); when Galahad next looks over, Magnus will be frowning, trying to make things look more... even by carefully cutting down some of the bigger pieces.
